(Qt) Full screen toggle does not take immediate effect

[orbea]

What happens?

With the Qt front end using either OpenGL or OpenGL ES the full screen toggle in the ui does not take effect until ppsspp is closed and started again.

It is however possible to toggle full screen immediately by double clicking the left mouse button.

I do not think vulkan is hooked up for the Qt frontend on linux so I haven't tested that. (#11628)

What should happen?

Toggling full screen in the ui should take immediate effect.

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

The keyboard shortcut and menu item both work fine on a Mac, at least.

@unknownbrackets It still doesn't work in linux. The keyboard shortcut does work though, but only for qt5.
